About the company
Primary Systems Inc., a for-profit Subchapter S corporation based in St. Louis, Missouri, provides Rauland Responder nurse call system maintenance, repair, upgrade, and installation services to the Department of Veterans Affairs as a prime contractor, competing in full-and-open procurements without set-aside designations across its federal portfolio.
Primary Systems operates exclusively as a prime contractor (100% of recent awards) focused on healthcare infrastructure for VA medical centers. The vendor's customer base is heavily concentrated within the VA system, with the top three Veterans Integrated Service Networks accounting for 70% of awards by count and 99% of combined potential value. Veterans Integrated Service Network 19 leads by dollar value with two awards totaling $2.4 million — including a $1.99 million definitive contract awarded August 2, 2024, for a complete Rauland Responder 4-to-Responder 5 system upgrade at the Oklahoma City VA Medical Center covering electrical relays, installation, labor, materials, warranty, and compliance with NFPA Life Safety Code standards, with completion scheduled for February 16, 2026. Veterans Integrated Service Network 15 anchors the award count with nine awards valued at $1.6 million combined, centered on recurring maintenance and repair delivery orders under a single-award Indefinite Delivery Contract (ceiling $352,960, ultimate completion September 18, 2029) issued September 19, 2024. Veterans Integrated Service Network 10 holds one contract for $127,692 in Rauland Responder 5 software maintenance at the Northern Indiana Health Care System, running through March 30, 2028. Recent representative work includes a $391,416 Responder 5 nurse call server software purchase order from VISN 19 (July 24, 2026), a $57,780 maintenance and repair delivery order from VISN 15 (September 19, 2026), and a $55,028 maintenance delivery order from VISN 15 (September 19, 2025).
Activity is intermittent across the recent five-year window — two awards in 2022, one in 2023, three in 2024, one in 2025, and two in 2026 — generating $4.1 million in combined potential value and $3.8 million in obligated dollars (92% execution rate). Three awards totaling $577 thousand reach ultimate completion within the next twenty-four months. The vendor places all work under full-and-open procurements; no set-aside designations appear across the portfolio. Primary Systems' capability footprint is narrowly specialized in Rauland Responder nurse call systems — the vendor does not appear in the source as a subcontractor, nor does it hold positions on government-wide vehicles or multiple-award schedules beyond its single-award VISN 15 IDIQ.
